A food web is the entirety of interrelated food chains in any and every ecosystem. This delicate balance is the connection between predator and prey‚ consumer and producer‚ and autotroph and heterotrophs. Food web’s also allows you to follow the direction of the flow of energy as each organism consumes each of their indicated food sources. For example‚ the energy from the sun is taken in by producers‚ such as ‚ trees‚ grass and fruit. Then goes to an autotroph would be eaten by a second trophic

Ecosystem Preservation versus Conservation Earth is composed of many different ecosystems and each one is a "dynamic complex of plant‚ animal‚ and micro-organism communities interacting with the non-living environment as a functional unit" (Protecting Threatened Ecosystems‚ 2004). These ecosystems are an intricate part of the human lifecycle as they provide us with our water‚ food and energy. Since mankind is in a take and take some more relationship with the ecosystems‚ many of them have had their

this project because in previous years and class we were just well known about the term “ecosystem” but now as we have done this project we have now learned various things about ecosystem in depth and that will help us in our course study in coming days. This project is based on term “ecosystem” and “Food chain” after going through it many will be able to answer these questions: * What is an ecosystem‚ and how can we study one? * Is the earth an open or closed system with respect to energy

The Action of Tiger Conservation As the population of tiger in the world dwindles nowadays‚ everyone has the responsibility for the conservation of tiger especially tiger range countries. Over the past 100 years‚ tiger numbers have declined by 95 percent which leave only 3‚200 and three sub-species have become extinct – with a fourth not seen in the wild for over 25 years (World Wild Fund for Nature [WWF] International‚ 2008). Since it is estimated that wild tiger number halved to 3‚200‚ we

What Shapes an Ecosystem? Ecosystems are made up of: * Biotic factors- all living parts of an ecosystem (plants‚ animals‚ bacteria) * Abiotic factors- all nonliving (but natural) parts of an ecosystem (soil‚ wind‚ water) These factors together (biotic and abiotic) determine which types of organisms can live in that particular ecosystem. A habitat- the place where an organism lives- includes both biotic and abiotic factors A niche includes both the habitat of an organism and its unique
